Apparently that's his girlfriend Blac Chyna (seriously) driving the supercar in this video. The Young Money rapper's Audi R8 is a one-of-one model and is the only gold R8 in the U.S. Tyga's Audi R8 packs a 4.2-liter V8 rated at 420hp. With a flashy appearance like that, you would think he would splurge a bit and go for the V10.
